Noob

Total noob question. but what if I copied all the files and folders over uncompressed though a wifi file explorer? I have access to every folder and file over wifi with dooblou wifi file explorer. Could this be rebuilt as a ext3 then flashed? I don't know anything so just throwing this out there to try and get this to where we want it.
[Android Q&A, Help & Troubleshooting] sadsephiroth:
Okay...

Using hxxp://xdaforums.com/showthread.php?t=1038819 , replace xx with tt, and the English flash tool from hxxp://topnotchtablets.com/Wopadi7-Firmware, I was able to flash and run CM7. Testing out now, according to root explorer, I have r/w in /system, and superuser grants root priv too. There are a few quirks, as some gui things don't look exactly right, but this is major progress. Steps I took to get this far

1. Unpack update.img downloaded from previous posts with Wendals. 4.2 unpack tool found hxxp://www.slatedroid.com/topic/22162-writable-system-for-rk29xxt760p71-et/

2. Replace boot.img and system.img with ones found at the CM7 post above.

3. Use english flash tool found above, erase then flash everything you can.

4. reboot and profit?

I am in no way responsible yada yada yada, I don't know much about how all this works, but got tired of waiting for a fix and took a chance. Any of you Linux gurus care to take a look and see if we can improve upon this?

Well, so far gapps works fine, but no wifi. Don't know anything about CM7 or building a rom in general. If someone wants to look at this, and see about getting wifi working, It is so far the only missing thing I've noticed to get our tablet fully working.
[Android Q&A, Help & Troubleshooting] sadsephiroth:
Also acceleration needs tweaked, left and right are fine but up and down are reversed, so when you go into the 3d gallery, you have to turn it upside down to zoom in pictures. But I tell you, this thing runs butter smooth. Scrolling issues I had with stock are gone, even with all animations on menu navigation are fast. I sent an email to the website hosting the firmware asking about these small issues, hopefully I can get in contact with a dev there, I will deff test this to help get it to a fully working state.
[Android Q&A, Help & Troubleshooting] drob311:
Im gonna give this a shot and swap out the stock libs/modules from the ptab with the ones in the rooted rom. Hopefully that will get wifi functioning... Ill keep the thread informed. Im also going to check into finding a compatable recovery or compiling a recovery... Good work! Hopefully the lib/modules swap will work. :)

Got CM7 booted now just trying to get things like wifi working

Ok, it seems that if I change the system partition in any way (even abd push a file) CM7 will not boot. Seems to me that something in the downloaded boot.img states what size /system is expected, because the device runs fine after a push until you reboot. Next task seems to be unpacking and modifying.

BIG NEWS!

Watch for upcoming post with both simple (first) and detailed (tomorrow) instructions for

CM7 WITH G-Apps working!

CM7 with GAPPS now |wip|

Minor setback after doing my mods, I discovered I lost su permission. Will get that fixed, but for the time being here is a quick guide to CM7 with google apps (only ones not available in market) working (no wifi yet) accelerometer was configured wrong at first, but I have that fixed in this build also added a couple small tweaks to build.prop

1st off, if you don't have the "Rock usb drivers" installed then look back for my post on installing this

ok, either download

these

files or use your own if you have done an rkdump start with those. If you use your own rkdump you just need to replace your system.img and boot.img from my above files

use rktool (found in above tutorial) to flash those items. make sure you check each box except the last one (Backup) select the proper img/file from yours/my rkdump

CM7 will boot as soon as everything is done

*Note*

upon first boot setup wizard will run, i suggest you hold in landscape with back/menu button on the left side.

*Note 2*

DO NOT REBOOT

until you do the following, otherwise, bootloop. use the file manager to navigate to /system/apps and install the apps listed below. they will say application not installed, well all except googleframeworks, which will install. I think that is the only one that really has to be installed but why not do all 18 for the fun!? I took the time to write them here, lol!

Awesome guys once wifi is working we will have a great tab on our hands!
[Android Q&A, Help & Troubleshooting] ParrotSquawk:
Is it just me...???

...or does anyone else find this tab works better witha stylus than with a fingertip?
[Android Q&A, Help & Troubleshooting] sadsephiroth:
Well

Somehow I flashed a bad bootloader and have myself softbricked. After I flashed a different image, not the ones listed here, m device went to reboot, nothing on screen. I reflashed with cm7 image and stock image as well, it says it flashes fine, but does not reset. When I connect to pc I do not have to hold menu to get it recognized, so I think it is somehow stuck in recovery/USB mode. I have let it drain all battery and tried again, no luck. About to try and crack it open and do a pin short to bring ti back to life. Has anyone else opened it up yet? Only asking so I can maybe see what it looks like inside before I chip the plastic opening up as I'm not so gentle sometimes, lol. I would just exchange it if any Kohl's in my area had 1 to exchange. No such luck. Again, my soft brick is NOT caused by anything being done here, I tried to load a different SDK's bootloader to see if it would work as I got ahold of one that had a possibility of working. So no worries to anyone trying things here. Just wondered if someone had opened this puppy up yet so I can do a pin shorting to get it into a mode I need to unbrick it. Thanks in advance if anyone can help out here. I anything I'll just get the nerve and do it myself and post a unbrick guide once I bring it back to life.

I joined you about 2 hours ago... oh well... thank goodness for warranties... "I took it out of the box and it wouldn't turn on." :) lmao
[Android Q&A, Help & Troubleshooting] chidave09:
That really sucks for you guys that bricked. Did you try the erase IDB button in the update tool? I'm guessing you already did, but wanted to throw it out there just in case. Also, I found I get the best results if I flash all partitions at once (except backup)

@Drob311 you mentioned the other day about trying to push some libs to system, what libs were you trying and where did you get them from? Could I get the originals if I flash the stock os and and copy them from adb shell. Also if I do this, what are the chances those will work?
[Android Q&A, Help & Troubleshooting] smarcin:
First of all, thanks for all the work going on here.

Second, sorry to hear of the softbricking going on.

Next, I had one of the Menard's tabs. Got it after Black Friday, so it wasn't much of a deal IMHO. I returned it and lucked into finding one at Kohls, who bless them, had sent me a 30% off offer, bringing it down to $84. And I had a $15 gift card, making it $69.

Here's my question: does anyone here have a Nook color to compare it with? I really like the ROMS available for the Color. You can get refurbed one from B & N's ebay store for $150. The Nook colors seem like a more solid feeling tab, but I'm wondering how performance would be. TIA if anyone has worked with a rooted Color and has any input.
[Android Q&A, Help & Troubleshooting] sadsephiroth:
Yeah

I tried erasing IDB, always flashed all partitions at once. I also got a tool that does upgrade and restore, neither worked. Something I notcied, when I flash IDB, it says 2048 to be flashed, and only counts to 1887. But when it rechecks, it says all is okay. Reading other people who had a soft brick with this chipset, the Nand pin short is about the only way to recover. I'm gonna give it a shot later tonight on that and see how it goes.
[Android Q&A, Help & Troubleshooting] sadsephiroth:
Taking apart is simple. I lightly pried up on the flaps around the menu/back buttons. Then all the way around to take off the faceplate. I counted 14 clips holding it in place, so be careful. There are 4 Philips screws in the corners underneath. Unscrewing these releases the bottom plate, allowing access to the inside. The construction is very well done. 2x 2100 mhAh 7.4v batteries. You have to be very careful to not rip off the wires going to the screen. When I removed the 4 screws, I had to pry the screen portion away from the bottom. After that, remove the plastic plate on the connectors. Make sure you removed your SD card as well. The volume and power buttons should come off the this point, too. There are then 4 more screws holding the motherboard to the bottom. They couldn't make it easy and give you access from the top. Nooo, they had to put a heatsink on top and hide everything underneath. This may be why I always felt heat in the bottom corner under the Home button when I ran something that pushed the tablet to its limit. Those four screws are held in with more torque then the other 4. 3 are visible when you have the tablet open like a sandwich, the other is hidden under the LCD connection by folding it closed then moving the screen backwards a little. Well, I get those four screws off and they have another heatspreader covering everything important form the bottom. So at this point I am at a loss as to anything I can do. I have tried to jump any of the pins I have access to, the only result if I jump two of the USB pins it disconnects and reconnects in the same mode. I have crossed the connection for the reset button to no result. I don't see a sfe enough to try way of removing either heatspreader to access the chips for a pin short to get factory mode. I'll give it a fresh go tomorrow and update.
[Android Q&A, Help & Troubleshooting] chidave09:
Good luck with that one! I love taking apart gadgets but I don't know about jumping random pins! Did you take a look at the data sheet I posted earlier? Maybe that has some kind of hint on what to jump. I guess I just got lucky, cause I had been flashing all kinds of partitions from different tablets to get something to work, got lots of bootloops, but no bricks like this. btw, the more detailed info about mounting the system, making changes, unpacking the boot info and other various tweaks will have to be tomarrow. I was having problems with a brick on my phone which was luckily fixed!
[Android Q&A, Help & Troubleshooting] delawaresace:
just want to let you know that I'm closely following this thread. I picked up a Polaroid Tab at Kohls on black Friday and would love to root it and just make it run better. unfortunately I don't have the time to do any testing my self, but I'll gladly donate to any project that helps out the cause. Thanks again to you guys for risking your tabs for what your doing.

Whats the deal with it not charging through the Mini USB? my dog ate the charger and I had to go MAKE a new one from parts from Radio Shack because the tab doesn't charge through the mini usb :(
[Android Q&A, Help & Troubleshooting] chidave09:
This upsets me too! I am curious if we could run some kind of jumper wires from battery to usb, or would that be to much hassle for the feature?

@sadsephiroth if you do get to any pins, look at chapter 2 of the data sheet I posted a few pages back. There is a diagram and a description of each pin. (hint look at the pins N15-N24 page 28) Looks very promising

Somewhat working cm7 with google framework

This is how to get cm7 w/root and google framework installed.:D

PLEASE READ EACH STEP BEFORE STARTING

I believe it is very noob friendly. If not, pm me with any questions, try to keep the thread as clean as possible! lol. Right now wifi still does not work. To get this to work I am GUESSING we need to somehow unpack the original system.img from the manufacture and pull the proper files to push to the new system.img. I really want to check out the above post by duvvid (excellent first post by the way) to try this guess. Anyway, lets get on with it.

UPDATE 12/22

1)

Make sure you have adb installed and working

!!!!!!!!!

2) You need the rockusb drivers and RK29 Update Tool which can be found HERE along with a guide on getting them installed and working.

3) Download THIS zip and extract it somewhere you can remember

4) Open up the RK29 Update Tool

5) Erase IDB (warning: erases everything except the sd card, but it is important)

6) Check every box except "Backup" and fill each one with the files downloaded in step 3.

7) Click "Run". This will send everything and boot your tab into recovery to do the operations. This is *not* the last step.

8) Silver Android logo? Default AOSP boot screen! And there's CM7 boot!

9) First thing it asks you to choose an app. Choose "Setup Wizard"

10) Complete setup, skipping the sign in. We can easily do this when we get wifi working. Setup will probably start over when you finish but will FC after 2nd run, which is fine.

11) Open the "File Manager" app and navigate to /system/app and click to install the following apps.

THIS MUST BE DONE BEFORE

any rebooting. Most will say not installed. That is fine, but for some reason if you don't do this you will have a bootloop. If any one is bored, I welcome you to try different combos to try and shorten this list:

12) Back out of the file manager and open the app drawer.

13) Open either "Market" or "Talk" or both (prefered) and back out (they may take a second to show up in launcher, but they will show)

14) Reboot and ENJOY!!!! Also if you had seen the lockscreen before the

reboot you would notice it is really screwed, well not any more.

ADDITIONAL INFO

I have most google apps from the market HERE. Just extract the zip, copy them to your sdcard, and install.

The tablet is already setup to appear as Nexus S in the market with Sprint as the carrier.

Link to folder with all files for tablet HERE

So then, I guess we can flash different loaders ONLY IF they are v1.65. Any other loader WILL BRICK your device

More Info Soon.

Most of my info to do all this came from THIS thread. Check it out if you get a chance. I also got a lot of info from many, many sites. Google search rk29xx or cramfs and at least the top 10 results of each were used as a reference tool!
[Android Q&A, Help & Troubleshooting] sadsephiroth:
+1 on the guide! Question though, is there a difference between RK29xxLoader(L)_DDR3_400Mhz_V1.64 and RK29xxLoader(L)_V2.06? I think my 2.4 image came with 2.06, and it might be what screwed up my first tablet.
[Android Q&A, Help & Troubleshooting] chidave09:
@sadsephiroth

I do believe there may be a difference, not sure. Do you have the p700 or 7200? These files are for the 700 and are from the 2.4 update. I have flashed a more generic loader file I found somewhere and had no problems. So, I don't think this is what caused the brick, but I am not 100% sure.
[Android Q&A, Help & Troubleshooting] sadsephiroth:
I have the 7200. I went through everything I did and my problem was I used a 2.08 loader that came with one of the flashing tools I used. It was for a later SDK then the one our tablet uses, with a EXT3 filesystem I believe.

On another note, I have been playing around with TetherGPS, and using it and Sygic along with wifi tether for my crappy Sprint Intercept, I now have working Turn by Turn GPS on a 7 inch screen. Is there anyway to find out everything our USB host mode supports? So far I have gotten smaller USB drives, a mouse, and a really old keyboard to work. Would there be a way to add game controller support if I have the proper modules? Plugging in a USB controller and USB bluetooth device would be the icing on the cake.

Hi, I'm new to XDA. Great work by the devs on this, risking devices. I was going to update firmware on Ptab7200. I noticed on update page it says latest firmware as 2.5.

But when I go to firmware page it shows as 2.4 firmware. I downloaded but I didn't install yet. Update.img is dated as 12/16/11. I haven't much experience for rooting/roms only optimus S and old touch pro. Not sure if someone would be able to look at this newer update.img.

[Android Q&A, Help & Troubleshooting] sadsephiroth:
Installed. It is 2.5, main differences I see right away, they changed the notification bar a little, added a clock to it. The screen density looks to have been changed slightly, or maybe just the icon size in the app drawer, either way it also seems more responsive to the touch, to me at least. It seems a little faster, I imagine the kernel has some changes made as well. I emailed asking for a changelog, but given past responses, it's unlikely, but worth a shot.

Also, went through the google apps list and narrowed it down to

Onetimeinitializer

SetupWizard

Talk

All that's required to prevent a bootloop on my end after updating to 2.5 then cm7. When I updated to 2.5, I did run almost every app at least once to look for differences, then flashed over CM7. Also, when going to the market through Dophin as desktop, for the first time I noticed featured tablet applications as an option. push installs orked just fine for most that I tried. I can't seem to get Flash 11 to run right without FC my browsers though.

---------- Post added at 08:17 PM ---------- Previous post was at 07:23 PM ----------

I managed to pull all of the lib files from the original 2.4 firmware! Alot easier than previously thought too, but more on that later. OK, so after I pulled the lib files I looked around and the I found 4 folders plus 170 other items. Checked the folders first and in "/modules" there is a file called wlan. I figured it sounded like a great first attempt, so I pushed it to my CM7 img and flashed. Went through setup and straight to settings. Tried to turn on wifi and it sits for a good few seconds saying "turning on" instead of "error". Looking good to me, until after a minute or so, it turns itself off. So, I go into wifi settings and turn it on again, takes a while and turns on with no networks showing. So, I press menu scan and still nothing. Short while later it turns off again. So, while some improvement, not quite there yet. I will be uploading "/system/lib" from the 2.4 update in a minute.

HERE is the /lib folder
